My invention consists in a horizontal slot, a, Figure 1, near the upper end, and-0n one side of the wicktube of a lamp, this slot to be of any required width suitable to the size of the lamp, and extending from one side of the wick-tube to the other. 1

Also, from the upper and outside edge of this slot, I have a metal guard or cap, b, Figures 2 and 3, extending down over the slot, at an angle frorn the tube! This cap and slot are for the purpose of conveying air to the flame, (after the wick is turned down below the slot in the wick-tube,) by which means the flame is extinguished. 7
